At the least, it often makes them feel empowered to speak out in favor of forgetting all about the issue, and emboldening them to push for whatever the politician pushes that they agree with. At least in the US, you can hop on social media and take a look at your local newspaper or news channel's posts, and see some of the truly insane comments (and I use insane here as in bringing up politics to promote their voted politician, or smear the other side, when the issue is something at a local level or unaffected by politics in any way).
